AZPF-12-022RQR12MB-S0040

The AZPF-12-022RQR12MB-S0040 is manufactured by Bosch Rexroth within the AZPF External High Performance Gear Pumps series. It supplies hydraulic power for automation systems by moving fluid each time the shaft rotates. Its displacement of 22.5 cm³ per revolution specifies the volume delivered per rotation and allows designers to predict flow rates. The unit uses an external gear arrangement, a configuration chosen for consistent volume output and ease of maintenance. Clockwise rotation is specified, so the inlet and outlet positions must match this direction when the pump is mounted. The drive shaft diameter is 17 mm, providing a defined interface for couplings or motors, and a maximum operating speed of 2500 rpm at pressure stage P2 limits the rotational velocity to maintain durability and efficiency.

For mounting, the assembly employs an SAE J744 82-2 (A) two-bolt flange that simplifies alignment with standard hydraulic motors, and the flange circle measures 82.55 mm to match corresponding housings. The design withstands intermittent pressures up to 140 bar, enabling short bursts of higher load during machine cycles. A shaft torque rating of 55 Nm indicates the mechanical load that can be applied without overstressing the gearing. The overall weight is 4.0 kg, allowing one-person handling during installation or service. Together these characteristics define pressure capability, structural limits, and mounting compatibility for reliable duty in automated hydraulic circuits.
